Обсуждение: pgsql: Stabilize timeline switch regression test.
Stabilize timeline switch regression test. Commit fef5b47f6b added the regression test to check whether a standby is able to follow a primary on a newer timeline when WAL archiving is enabled. But the buildfarm member florican reported that this test failed because the requested WAL segment was removed and replication failed. This is a timing issue. Since neither replication slot is used nor wal_keep_size is set in the test, checkpoint could remove the WAL segment that's still necessary for replication. This commit stabilizes the test by setting wal_keep_size. Back-patch to v13 where the regression test that this commit stabilizes was added.
